This bill aims to increase transparency in the Congressional Budget Office's (CBO) cost analysis and scoring processes. It mandates that the CBO Director make publicly available the fiscal and mathematical models , data, and other computational details used in estimating the costs and effects of legislation. This requirement extends to all policy models, data preparation routines, and any updates to these tools. A crucial provision of the bill is the requirement for the CBO to provide the specific data, programs, models, and assumptions underlying each cost estimate. This information must be presented in a manner that allows individuals not employed by the CBO to replicate the estimates independently . For any data that cannot be disclosed due to statutory restrictions, the CBO must still provide a complete list of variables, descriptive statistics, and a reference to the relevant non-disclosure statute, along with contact information for those with unrestricted access. The amendments made by this Act will take effect six months after its enactment.
